Roborock S7 Pro Ultra directly connected to clean and dirt water pipes. Fully autonomous.

You can see here how i’ve made the S7 fully autonomous by attaching it to the clean water and dirt water pipes of my house. I’ve used an external airpump and a relais to allow the Ultra base’s logic board to switch on the pump without damaging the board itself.
The dirt tank is totally unused, so no smell, no bad water remaining in the tank. The tank remains like new.

Incredible job. Congratulations from Brazil!!!

Nice. I'm going to get my "ultra" robot soon and i'm thinking of doing a similar installation.

[@scrampker]

For my setup I just used a $3 float valve for the clean water. The dirty water tank can also use float trigger, but I am just using a timer.

Hi Steven. I had also done that like you, for my old Narwal, but my goal now was to completely avoid using the dirty water tank.

[@scrampker]

@@maxsupergiovane I like that as well :) prevent the sludge from building up. I think to properly automate the tank system, cleaners would need to be introduced as well. Perhaps a gravity-fed bottle-dispenser for the clean water tank would be enough, then as it flows through the rest of the plumbing it keeps things clean. I always use a cleaner with my robot, as it's much more effective at the task, not to mention the dirty tank smells much better.
Good job. Eventually when I finish my system I will post my results to share with you.

@@scrampker I've mantained the clean water tank, exactly to be able to add detergent as needed. It works very well and that little solenoid allow the clean water tank to be half full everytime. Not to mention, that i've put a Shelly water leak detector near the robot, to warn in case of leaking. ;-)

[@SC-yy4sw]

what kind of pump are you using to empty the grey water tank ? A small peristaltic one ?

[@scrampker]

@@SC-yy4sw none, actually. I bought the official kit. This diy is far too much hassle. I'm reusing my parts in other projects.

AWESOME !!!

Buongiorno, come prestazioni di aspirazione e lavaggio (aldilà della parte di riconoscimento oggetti e videocamera) hai preferito il roborock o l'x1 omni? Io credo che questo roborock abbia una marcia in più su entrambe le caratteristiche.

[@maxsupergiovane]

Ciao Filippo. In definitiva, il Roborock. Non che l'X1 lavi male, ma lava un po' meglio il Roborock. Probabilmente avevo un po' sopravvalutato l'efficacia mops rotanti.

[@jaimebtta2585]

How did you get it to recognize the tanks?

[@maxsupergiovane]

Hi
The tanks remain in place. So no issues!

[@robertomozzicato249]

Grande! Stavo cercando di farlo anch'io, ma non capisco che tipo di pompa devo usare per aspirare l'acqua di scarico. Nel mio caso ( come credo anche nel tuo) c'è una vaschetta nella base sotto il robot che serve alla pulizia dei panni. Una volta lavati la pompa dovrebbe riuscire ad aspirare l'acqua dal basso e spingerla verso lo scarico.
Tu che pompa hai usato?

[@maxsupergiovane]

Ciao. Una qualsiasi pompa, che però sia autoadescante, cioè in grado di aspirare l’acqua partendo dall’aspirazione dell’aria. Io ne ho usata una a membrana, l’avevo presa su Amazon.

[@robertomozzicato249]

@@maxsupergiovane Presa, grazie 1000! "Autoadescante" era la parola chiave che mi mancava per trovare quello che mi serviva.

[@maxsupergiovane]

Ovviamente si perde la garanzia. Ero consapevole, ma così è veramente molto più comodo.
